Cat of Venus

Cool, ancient Felyne holy sword from when they ruled the world. A Felyne's dream.
A re-creation of a great sword that Felynes whisper is the holy sword painted in an ancient mural as proof that Felynes once ruled the world. A large amount of lightning jelly is used in the golden-shining blade, and anyone cut by it feels a shock through their whole body, as if struck by lightning.
